Motor controller and method for controlling a motor after a power-loss event
First Claim
1. A motor controller configured to be coupled to a variable speed motor, said motor controller comprising a computing device configured to:
- determine power is being supplied to the motor controller after a power-loss event;
determine whether user input information was received before the power-loss event; and
operate the motor in accordance with a predetermined operating schedule such that said computing device operates the motor at a first speed for a first time period, and after completion of the first time period, said computing device operates the motor at a second speed for a second time period.

Abstract
A motor controller and methods of controlling a variable speed motor using the motor controller after a power-loss event are described. The motor controller is configured to be coupled to a motor. The motor controller includes a computing device configured to determine power is being supplied to the motor controller a power-loss event. The computing device is also configured to operate the motor in accordance with a predetermined operating schedule such that the computing device operates the motor at a first speed for a first time period, and after completion of the first time period, the computing device operates the motor at a second speed for a second time period.

15. A non-transitory computer-readable storage device having processor-executable instructions embodied thereon, enabling control of a variable speed motor using a motor controller after a power-loss event, the motor controller including a computing device, wherein when executed by the computing device, the processor-executable instructions cause the computing device to:
-
determine power is being supplied to the motor controller after the power-loss event; determine whether user input information was received before the power-loss event; and operate the motor in accordance with a predetermined operating schedule such that the computing device operates the motor at a first speed for a first time period, and after completion of the first time period, the computing device operates the motor at a second speed for a second time period. - View Dependent Claims (16, 17)

18. A motor controller configured to be coupled to a variable speed motor, said motor controller comprising a computing device configured to:
-
determine power is being supplied to the motor controller after a power-loss event, wherein said computing device is coupled to an external timer configured to supply power to the motor controller starting at a first time of day and to stop supplying power from the motor controller at a second time of day, said computing device is further configured to; determine power is being supplied to the motor controller at the first time of day; operate the motor at a first speed for a first time period; after completion of the first time period, operate the motor at a second speed for a second time period; and cease operation of the motor when the external timer stops supplying power at the second time of day.
